WPF ScrollViewer for ListBox -> Performance issues

I'm trying to create grid with listbox with Scrollbar. It's done somehow like that:

<Grid>
<ListBox Name="xxx" ItemsSource="{Binding}" ScrollViewer.HorizontalScrollBarVisibility="Disabled" ScrollViewer.VerticalScrollBarVisibility="Visible">
....
</ListBox>
</Grid>

The problem is that if I use scrollbar, then the size of bar-button jumps back and forward within scrolling. If I remove ScrollViewer from properties and instead put ListBox in ScrollViewer tag, then everything is working perfect, except of terrible performance of rerendering UI (resize, move window, resource consuming). According to google it does "disable virtualization". This sounds crazy that there's no simple solution to get properly working scrollbar and usable UI without issues.

Is there compromise for both of these things? Virtualization + properly working scrollviewer with fixed size of scrollbar button.

This is probably because the items in your ListView are not of the same size. What are you trying to display with this ListView? – user3596113 Nov 04 '14 at 08:07
Yes, they're not the same size. Just displaying items with several paragraphs of text each. – dimon222 Nov 04 '14 at 11:12
You could try to make each item only one line of text (just for testing reasons). – user3596113 Nov 04 '14 at 14:12
